    <p>There is a fundamental problem with any wiki, and it's not easy
      to fix.<br>
    </p>
    <p>Each page was obviously last edited by one user and one user only
      - they had the chance to change anything in it.  In some cases
      there is a difference of opinion about how to do something, some
      editors (Harry Wood is an obvious example that springs to mind) do
      a great job of both (a) saying that there isn't consensus and (b)
      suggesting what new mappers ought to do - even if that is to
      choose between two options.  Unfortunately some wiki editors don't
      understand this, think that they're right and everyone else is
      wrong and (in the manner of xkcd's "Duty Calls") ensure that the
      wiki represents their opinion, and not the opposing view.</p>
    <p>The edit that you're talking about is an example of this:<br>
    </p>
    <p><a class="moz-txt-link-freetext" href="https://wiki.openstreetmap.org/w/index.php?title=Semi-colon_value_separator&type=revision&diff=1131976&oldid=1131680">https://wiki.openstreetmap.org/w/index.php?title=Semi-colon_value_separator&type=revision&diff=1131976&oldid=1131680</a></p>
    <p>In this case that wiki contributor was banned from editing the
      wiki (at least), but that's a very drastic solution, and they're
      not the only problem - at any time search through the wiki's
      "recent changes" for talk page edits and you see complaints about
      this sort of behaviour.</p>

    <p>Best Regards,</p>
